Based on this mentality of designing, traditional magnetic refrigerator complex structure, power consumption, refrigeration extreme difference, cannot meet general refrigeration for refrigerator requirement.
The magnetic refrigeration structure that the present invention proposes does not consider how to strengthen the refrigeration of single magnetic working medium, but go to deal with problems from macroscopic perspective, dozens of magnetic working medium is serially connected, allow wherein the part pyrogenicity that is magnetized, a part is by demagnetization refrigeration in addition, and both assist mutually, the concept of refrigeration machine are transformed into the concept of " heat energy elevator ", make the two ends of magnetic string form cold junction and hot junction, cold junction temperature can reach the effect of refrigeration completely.
In order to make technical scheme of the present invention be more prone to be understood, first the concept of " heat energy elevator " is simply set forth. For an object, if direct " taking away " its heat energy, the atom that makes its a certain position around electronic vibration (energy level) weakens, and finally causes the electronic vibration (energy level) of this object entirety to weaken, and this is the principle of tradition refrigeration. If to this object, not direct " taking away " its heat energy, just make the heat energy distribution of this object inhomogeneous by a kind of " heat energy lifting device " (heat energy carrying is mobile), such as carrying by heat, by the constantly up carrying of the heat of object bottom, make its lower end temperature reduce by 20 DEG C, upper end temperature raises 20 DEG C, this just produces so-called cold junction and hot junction, now this object " is not given or take away " heat (total heat energy of object is constant), but cold junction has reached the requirement of refrigeration completely. Below, technical scheme of the present invention is described in detail.
Based on above-mentioned principle, the invention discloses a kind of rotary string utmost point magnetic refrigerating system, as shown in Figure 1, comprise magnetic string 200, the heat insultating cavity 210 that this magnetic string 200 is arranged by multiple connections forms, and each heat insultating cavity 210 is setting up and down, and each heat insultating cavity inside is provided with magnetic working medium 2 20.
